FIRE BOX.

Application filed. March 30, 1820.

T 0 all whom it may concern:

Be it known that I, ROBERT B. TAYLOR, a citizen of the United States, residing at Baltimore, State of Maryland, have invented new and useful Improvements in Fire Boxes, of which the following is a specification.

This invention relates to fire box arches, and comprehends a construction wherein the bricks of the arch are associated to prevent of their being separated incident to the vibration of the locomotive. Arch bricks with which I am familiar, are provided with a narrow shoulder that rests upon the water cooled pipe and the vibrations of the locomotive causes these bricks to separate and fall into the fire before adhesion takes place, thus resulting in the loss of the bricks as well as other troubles.

It is therefore the purpose of this invention to construct the bricks used in the production of the arch, in a manner whereby an overlapped joint is provided for the meeting ends of the bricks, thereby making it impossible for the bricks to become separated incident to the vibration of the locomotive.

The nature and advantages of the invention will be better understood when the following detailed description is read in connection with the accompanying drawings, the invention residing in the construction, combination and arrangement of parts as claimed.

In the drawings forming part of this specification, like numerals of reference indicate similar parts in the several views and wherein Figure 1 is a plan view of one of the arch sections constructed in accordance with my invention.

Figure 2 is a longitudinal sectional view therethrough.

Figure 3 is a plan view of one of the bricks used in the construction of the arch.

Figure 4 is an edge elevation.

Figure 5 is an end elevation of one of the bricks.

Figure 6 is a transverse sectional view through one of the bricks.

Figure 7 is a plan view of the arch show ing a modified construction.

Figure 8 is an edge elevation.

The arch contemplated by the invention is made up of the desired number of sections such as illustrated in Figure 1, each sec- Serial No. 369,912.

tion preferably including three bricks of the type shown. The two end bricksof each section as indicated at 10 while the intermediate brick is indicated at 11. The-meetingends of these bricks are cut away as at 12- to receive a portion of the water cooled pipe 13 in the usual manner, these cutaway portions defining shoulders 15 which rest upon the pipes as illustrated. With a view of firmly holding the bricks in arched formation, and thereby preventing these bricks from becoming separated incident to the vibrations of the locomotive, I provide each of the end bricks 10 upon one side with a thickened or raised portion 16, each of which is formed or provided with a recess 17. Carried upon one side of the intermediate brick 11 and at each end thereof is a pair of lugs 18, each pair projecting an appreciable distance beyond the adjacent end of the brick. These lugs 18 are, when the bricks are arranged in arched formation re ceived by the recesses 17 thus providing an overlapped joint at the meeting ends of the bricks as is obvious. In other words, the lugs 18 bridge the meeting ends of the respective bricks l0 and 11 and overlie the water cooled pipe 13, an arrangement which positively prohibit-s separation of the bricks incident to the vibration of the locomotive, thus preventing the bricks from dropping into the fire resulting in numerous troubles.

In Figures 7 and 8 I have illustrated a modified form of the invention, wherein the respective sections of the arch indicated at 20, have their meeting ends cut away as at 21 to receive a portion of the water cooled pipe 23, these cut away portions defining shoulders24. which rest upon the pipe as illustrated. In this form of the invention lugs 25 arranged in pairs project from one end of each of the end sections of the arch, while similar lugs 26 project in pairs from both ends of the intermediate section of the arch, and when the sections are arranged end to end, the lugs 25 and 26 bridge the meeting joints between the sections, and bear upon the surface of the adjacent section as clearly shown in Figure 7. It is to be understood that any number of bricks may be employed in the production of the arch, and the lugs carried by the respective sections are arranged in a proper manner to overlie or bridge the joint between the ends of the sections.

While it is believed that from the foregoing description the nature and advantages of the invention will be readily apparent, I desireto have it understood that What is herein shown and described is I I1E I61y illustrative, and that I do not limit myself in this connection and that/such changes may 3e resorted to When desired as fall Within the scope of What is claimed. w Having thus described my invention What I claim as new is 4 7 A jfire box arch comprising spaced sections and an intermediate section, said sectionsbeing arranged in end to end relation, the adjacent ends 01' the respective sections being cut away, said cut away portions of 15v opening at the ends of the sections, and lugs carried by the intermediate section and projecting beyond the ends thereof and adapted to be received by said slots, overlapping i the spaced sections for the purpose] specified. 1 In testimonywher'eof I aifix my signature.
